Uncertainty, whether sparked by financial turmoil, pandemics, geopolitical tensions, or abrupt technological shifts, exerts pressures that steer governments and voters toward protectionist measures. Such protectionism emerges from fear, political incentives, and calculated strategy. This article explores the forces that revive protectionism during difficult periods, illustrates them through historical and contemporary examples, analyzes the economic mechanisms and outcomes involved, and presents policy alternatives that can lessen the impulse to withdraw behind trade barriers.Historical trends and recent instancesProtectionism is not a modern anomaly. The 1930s Smoot-Hawley tariffs are the classic example: the United States raised tariffs in an effort to shield domestic…

Oceans serve as the world’s leading force in regulating climateThe global ocean spans about 71% of Earth’s surface and functions as the planet’s chief climate moderator, absorbing and redistributing heat and carbon to soften temperature fluctuations, shape weather systems, and maintain essential life-supporting biogeochemical processes. Two key functions are especially notable.Heat storage: The ocean has absorbed most of the surplus heat generated by greenhouse gas emissions—widely assessed as exceeding 90% of the planet’s accumulated excess warmth—thereby tempering atmospheric temperature rises while introducing long-lasting thermal inertia that commits the climate system to future shifts.Carbon sink: The ocean takes in a substantial…
